Description

Technical Field

[0001] This utility model relates to the field of laser ranging module technology, specifically to a laser ranging module adjustment mechanism. Background Technology

[0002] Laser ranging uses a laser as a light source for distance measurement. Based on the laser's operating mode, it is divided into continuous lasers and pulsed lasers. Gas lasers such as helium-neon, argon-ion, and krypton-cadmium operate in continuous output mode and are used for phase-type laser ranging; dual heterojunction gallium arsenide semiconductor lasers are used for infrared ranging; solid-state lasers such as ruby ​​and neodymium glass are used for pulsed laser ranging. Due to the good monochromaticity and strong directionality of lasers, coupled with the semiconductor integration of electronic circuits, laser rangefinders, compared with photoelectric rangefinders, can not only operate day and night but also improve ranging accuracy.

[0003] Chinese utility model patent CN221880999U discloses a height-adjustable laser ranging module, including a support base. A limiting groove is formed on the upper surface of the support base, and a damping spring is fixedly installed on the inner bottom wall of the limiting groove. A sponge damping plate is fixedly installed on one side of the damping spring, and a limiting support plate is fixedly installed on the upper surface of the sponge damping plate. This height-adjustable laser ranging module is configured through the cooperation of a telescopic main rod, a snap-fit ​​slot, a telescopic secondary rod, a limiting groove, a damping spring, a button, a damping shaft, and the laser rangefinder body. By pressing the button, the damping spring is compressed, changing the position of the snap-fit ​​slot, thereby adjusting the height of the laser ranging module. The user can then adjust the laser ranging angle using the damping shaft, thus achieving the function of adjusting the height and angle of the laser ranging module.

[0004] However, during use, the position and number of the snap-fit ​​slots are fixed, which means that the position of the telescopic auxiliary rod is predetermined and cannot be adjusted to any height. This results in certain limitations of the device, which cannot meet production requirements. Therefore, a laser ranging module adjustment mechanism is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a laser ranging module adjustment mechanism that has the advantage of arbitrary height adjustment. It solves the problem that the position and number of locking slots in existing adjustment mechanisms are fixed, which leads to the telescopic auxiliary rod adjustment position being pre-designed and unable to achieve arbitrary height adjustment, resulting in certain limitations of the device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser ranging module adjustment mechanism, comprising a triangular support frame and a support cylinder fixedly connected to the top of the triangular support frame, wherein a laser ranging module is disposed on the top of the support cylinder, and a height adjustment structure capable of adjusting the laser ranging module to any height is disposed inside the support cylinder;

[0007] The height adjustment structure includes a drive box fixedly connected to the top of the support cylinder. The support cylinder has a threaded rod extending to the top of the drive box. A lifting plate is fixedly connected to the top of the threaded rod. A threaded sleeve is rotatably connected inside the drive box. A worm gear is fixedly installed on the outside of the threaded sleeve. A transmission worm gear meshing with the worm gear is rotatably connected inside the drive box.

[0008] Furthermore, the threaded rod and the threaded sleeve are connected by a threaded connection, and a handwheel capable of driving the transmission worm gear is rotatably connected to the front of the drive box.

[0009] Furthermore, a limiting plate is rotatably connected to the bottom end of the threaded rod, and limiting blocks extending into the support cylinder are fixedly connected to both the left and right sides of the limiting plate. A limiting groove adapted to the limiting block is opened on the inner wall of the support cylinder.

[0010] Furthermore, a rotating plate is rotatably connected inside the lifting plate, a movable seat is slidably connected inside the lifting plate, a connecting rod is rotatably connected between the movable seat and the rotating plate, and an electric push rod is rotatably connected between the rotating plate and the lifting plate.

[0011] Furthermore, there are two movable seats, which are symmetrically distributed on the left and right sides of the rotating plate, and the end of the connecting rod away from the rotating plate is located at the center of the movable seat.

[0012] Furthermore, a clamping plate is slidably connected to the upper surface of the lifting plate, and a connecting block is fixedly connected between the clamping plate and the movable seat. An movable groove adapted to the connecting block is opened on the upper surface of the lifting plate.

[0013] Furthermore, the laser ranging module abuts against the opposite sides of the two clamping plates, and anti-slip pads are fixedly connected to the opposite sides of the two clamping plates.

[0014] Furthermore, a positioning guide rail is fixedly connected to the inner bottom wall of the lifting plate, and a positioning slide block that is slidably connected to the positioning guide rail is fixedly connected to the bottom of the movable seat.

[0015] Compared with the prior art, this utility model provides a laser ranging module adjustment mechanism, which has the following beneficial effects:

[0016] 1. The laser ranging module adjustment mechanism drives the transmission worm gear to rotate by turning the handwheel, which in turn drives the worm wheel and threaded sleeve to rotate. This allows the threaded sleeve to rotate the threaded rod while simultaneously moving up and down, thereby driving the lifting plate and the laser ranging module to move up and down. This achieves the effect of adjusting the laser ranging module to any height, while also facilitating fine-tuning and improving the practicality of the device.

[0017] 2. The laser ranging module adjustment mechanism uses an electric push rod to drive the rotating plate to rotate. At this time, the rotating plate can simultaneously drive the two moving seats to move, so that the two clamping plates can easily clamp and fix the laser ranging module, achieving the effect of fixing the laser ranging module for installation. At the same time, it is convenient to remove the laser ranging module. This solves the problem that the position and number of the snap-fit ​​slots are fixed, which leads to the fixed position of the telescopic auxiliary rod adjustment and the inability to achieve arbitrary height adjustment, resulting in certain limitations of the device.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1 to 3This embodiment of a laser ranging module adjustment mechanism includes a triangular support frame 1 and a support cylinder 2 fixedly connected to the top of the triangular support frame 1. A laser ranging module 3 is disposed on the top of the support cylinder 2.

The height adjustment structure includes a drive box 4 fixedly connected to the top of the support cylinder 2. A threaded rod 5 extending to the top of the drive box 4 is disposed inside the support cylinder 2. A lifting plate 6 is fixedly connected to the top of the threaded rod 5. A threaded sleeve 7 is rotatably connected inside the drive box 4. A worm gear 8 is fixedly installed on the outside of the threaded sleeve 7. A transmission worm 9 meshing with the worm gear 8 is rotatably connected inside the drive box 4.

[0025] Specifically, the threaded rod 5 and the threaded sleeve 7 are connected by a threaded connection. The front of the drive box 4 is rotatably connected to a handwheel 10 that can drive the transmission worm gear 9 to rotate. The bottom end of the threaded rod 5 is rotatably connected to a limiting plate 11. The left and right sides of the limiting plate 11 are fixedly connected to limiting blocks that extend into the support cylinder 2. The inner wall of the support cylinder 2 is provided with a limiting groove that matches the limiting block.

[0026] It should be noted that by rotating the handwheel 10, the transmission worm 9 is driven to rotate, and then the transmission worm 9 drives the worm wheel 8 and the threaded sleeve 7 to rotate, so that the threaded sleeve 7 can drive the threaded rod 5 to rotate and move up and down at the same time, thereby driving the lifting plate 6 and the laser ranging module 3 to move up and down.

[0027] It should be noted that, due to the self-locking property between the transmission worm 9 and the worm wheel 8, the transmission worm 9 can be prevented from rotating unexpectedly, thus improving stability to a certain extent.

[0028] Please see Figure 1 , Figure 2 and Figure 4 In this embodiment, a rotating plate 12 is rotatably connected inside the lifting plate 6, and a movable seat 13 is slidably connected inside the lifting plate 6.

There are two movable seats 13, which are symmetrically distributed on the left and right sides of the rotating plate 12. The end of the connecting rod 14 away from the rotating plate 12 is located at the center of the movable seat 13.

[0029] Specifically, a clamping plate 16 is slidably connected to the upper surface of the lifting plate 6, and a connecting block is fixedly connected between the clamping plate 16 and the moving seat 13. An active groove adapted to the connecting block is opened on the upper surface of the lifting plate 6. The laser ranging module 3 abuts against the opposite side of the two clamping plates 16 respectively, and anti-slip pads are fixedly connected to the opposite side of the two clamping plates 16.

[0030] It should be noted that a positioning guide rail 17 is fixedly connected to the inner bottom wall of the lifting plate 6, and a positioning slide block that is slidably connected to the positioning guide rail 17 is fixedly connected to the bottom of the moving seat 13.

[0031] It should be noted that the electric push rod 15 is located at the bottom of the movable seat 13, and there are two positioning guide rails 17. By setting the positioning guide rails 17, the stability of the movable seat 13 can be improved.

[0032] The working principle of the above embodiments is as follows:

[0033] First, the staff places the device in a suitable position and supports the entire device with the triangular support frame 1. At this time, the entire device is in a stable state. Then, the laser ranging module 3 is placed on the lifting plate 6. After that, the electric push rod 15 is started to drive the rotating plate 12 to rotate clockwise. At this time, the two clamping plates 16 clamp and fix the laser ranging module 3. Then, the staff can manually turn the handwheel 10 to adjust the laser ranging module 3 to a suitable height.

[0034] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions.
